Qualified Products Lists

    Qualified Products Lists are maintained by the Department as part of the quality assurance program for construction materials. The Materials and Testing Section is responsible for updating and maintaining the Qualified Products List Manual and for evaluating most new products for inclusion in this listing.  The maintenance, revision and publishing of the manual is handled by the Materials Qualifications Unit.  The QPL Manual is updated quarterly and all manual holders receive a copy of the revisions.
    The Qualified Products Lists have been developed for those materials which require more than normal sampling and testing, such as materials requiring source approval, performance evaluation, in-service evaluation, long-term testing, etc.  The QPL provides for a thorough evaluation on a one-time basis rather than each time the product is used.  After initial evaluation and placement on the QPL, only short-term "identification" tests and/or certifications are usually required to ensure continued conformance to specifications.
    A qualification procedure has been established for each QPL.  This procedure contains a list of information required from the manufacturer of the product, a Qualified Product Evaluation form, sample size, laboratory testing time, field testing time, tests performed, specification requirements and project acceptance requirements.
    Manufacturer's representatives who wish to have products placed on a Qualified Products List must submit the Qualified Product Evaluation form, all information listed in the qualification procedure and a sample to the proper QPL coordinator at the Materials and Testing Section.  A list of QPL coordinators is located in the front of the QPL Manual.  The list of QPL coordinators may be obtained free of charge by contacting the Materials Qualifications Unit at (225) 248-4111.
    For further QPL information, contact the Materials and Testing Section, 5080 Florida Blvd., Baton Rouge, LA 70806, phone (225) 248-4131.  The QPL Manual is available free of charge to:
